If you're looking for an excuse to buy RAM, this deal is all the justification you need. Adata's 16GB (2x8GB) XPG Gammix D30 DDR4-3000 memory kit is on sale at Newegg for $56.99, which is not only a great bargain, it's also now the least expensive 16GB DDR4 kit around.
To see how this deal compares to other RAM, I performed a search for all 16GB DDR4 memory kits on Newegg, and this one undercuts them all. The next least expensive kit is an off-brand Timetec 16GB DDR4-2666 kit.
You're saving $23 over this kit's list price, and around $11 versus other 16GB DDR4-3000 kits. Sure, we're not talking about boatloads of cash here, but this is a fantastic price.
I'm not enamored with the "edgy wing-shaped" design of the heatspreader, but in most PCs, you don't get a great look at the RAM anyway. And if you happen to be into ninja stars, you'll probably have the exact opposite option as I do.
For anyone wonder, the answer is 'yes', RAM speed and capacity matter for gaming. This kit strikes a good balance between both, at a palatable price.
